The nanoscale topographic features of surfaces, such as vertical, lateral, and multiscale structures, are essential for understanding and identifying correlations with properties in various applications. These features are critical in applications ranging from biomedical devices to electronic components, as they play a significant role in determining the functionality of these systems. Despite the

Dimethyl sulfoxide in a Langmuir trough Appl. Surf. Sci. (IF 6.3) Pub Date : 2024-07-02 Alexander Sorokin, Larissa Maiorova, Maksim Zavalishin
Dimethyl sulfoxide (DMSO) is sometimes used as a solvent in the preparation of Langmuir-Blodgett (LB) films. By analogy with standard volatile solvents, it is often assumed that DMSO has no further effect once the solute molecules are distributed over the subphase surface. We hypothesized that this is not always the case and that DMSO may play an important role by remaining on the surface after spreading
